Any experienced camper will recommend that you put a layer of comfort between your sleeping bag and the cold hard ground. When the temperature drops and you settle in for the night, you'll be glad you packed one. We stock a variety of sleeping mats including foam, insulated foam, inflatable, and self-inflating. Also worth the three pound investment, are the emergency blanket and thermal sleeping bag. They weigh practically nothing and can literally save your life in an emergency.
